Less elongation
25 February 2015
When one of the largest asphalt mills in the Netherlands experienced reliability issues with a 16B-1 drive chain used on a conveyor for transporting raw materials, it turned to Tsubaki for a solution.
The root cause was established as a lack of lubrication reaching the bearing faces of the chain which was causing chain elongation and subsequent failure. The proposed solution was to install the latest RS16B-1 GT4 Winner chain in order to reduce wear and prolong the operating life.
As part of the solution, Tsubaki agreed to take part in a KG-test comparison with two other premium brands of chain. The test ran for 1000 hours in the real-life application. The results showed that one competitor chain suffered from 2.2% elongation and the other from 1.51%, while the GT4 Winner chain had only seen a 1.29% increase in length. This demonstrated that the GT4 Winner chain had 15% less elongation than the first brand and 35% less than the second.
